The following statement accurately describes vaccination.

• A. It prevents viruses from growing in the body, but is not available for all viruses
• B. It cures all infections
• C. It eliminates viruses instantly
• D. It is harmful to salon clients

Answer: (A)

Vaccination trains the immune system to recognize viruses and respond quickly, which helps prevent infection or greatly reduce illness by limiting viral replication in the body. Because vaccines are specific to particular viruses, they aren’t available for every virus—developing safe and effective vaccines for each pathogen takes time and research. Vaccines don’t cure infections, and they don’t instantly eliminate viruses if exposure occurs. When given under proper medical safety practices, vaccines are generally safe for salon clients, with serious harms being rare.
